Please tell us some basic information before asking for help:

In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
========================================
I've tried resetting the phone several times. I made certain to keep only the basic apps.
The problem appears to be permanent. The camera worked for about 4 months.
The message is always the same : "error camera is not ready"

Hi @Grant123
Thank you for reaching out!
Does this issue appear on the stock camera or on other third-party camera apps as well? Please try these troubleshooting steps:
1.Clearing cache & storage of Camera app (long press "Camera">App Info>Storage & memory>Clear cache/Clear storage), then if is also related to some third-party app, try to re-install and check again.
3. Also, if the error persist I will recommend you to try a complete Factory Reset. Please remember to back up your data before performing a factory reset.
Settings>System>Reset options>Erase all data(factory reset)
Also, make sure that your phone is updated to the latest firmware version. Thank you!
